Abstract: Dynamic power management is emerging as a technique for meeting stringent power and performance requirements of the portable system by changing processor speed and voltage at run-time depending on the need of the applications running. This article introduces a scheme relating to dynamic power management for embedded system, and reveals particularly two crucial problems in this scheme: how to detect dynamically and how to expand the detecting data from processor.
